Beovox CX50

INTRODUCTION

This is a guide on how to upcycle a Beovox CX50 loudspeaker using a BeoCreate 4-Channel amplifier and a Raspberry Pi.

The upcycling process will take roughly two hours and we advise you to prepare for the project by having all the required items at hand.

PARTS

· Beovox CX50

· BeoCreate 4-Channel Amplifier

· Raspberry Pi 3

· MicroSD card (at least 4GB)

· Power plug & supply (page 3)

· 3D printed parts (page 3)

· Hot glue or epoxy glue

· Screws and spacers

to fit the 3D printed frame

· Two insulated wires for the

power connector (20cm)

TOOLS

· Soldering iron

· Screwdrivers

· Glue gun

· Wirecutters

· Wirestripper

· Hacksaw

STEP ONE

4

From the front of the speaker, remove the fabric covers.

From the reverse side, first unscrew the back plate.

5

Remove the dampening material. Cut all of the wires connecting the drivers to the back plate.

6

NOTE

Evaluate the state of the speaker drivers and make sure they are in good condition. If the speaker foams are damaged a repair is needed.

You can either:a) refoam yourself (refoaming kits and instructions are available here: (link to come))

b) buy new drivers compatiable with the original (link to come)

c) get them repaired by a professional (link to come)

STEP TWO

8

Remove the original plastic speaker connector with a saw. Make sure to cut

through the wider end, upon which you will be later placing the 3D printed puck.

Screw the power plug into the 3D printed puck.

9

Apply glue to the 3D printed holder. Make sure to cover all the inner walls with a

vast amount of glue.

Place the parts upon the opening you just created. Make sure they fit in as tightly as

possible.

10

Strip the insulated wires you reserved for the power connector, so that approximately

1cm of wire is exposed.

Check the polarity of the power supply (which is +/-) and identify the

corresponding pin on the power plug. Solder both wires to the power plug pins.

STEP THREE

12

Strip the wires coming from the drivers, so that again approximately 1 cm of wire is

exposed.

Place the Raspberry Pi upon the BeoCreate 4-Channel Amplifier.

13

Install spacers to three corners of topside of the Pi using the supplied nuts as seen in the pictures (there are both nuts and screws in

the box).

Screw the 4CA to the frame. Don’t use screws in the holes that will be covered by

the spacers

14

Install the Pi onto the 4CA. The spacers won’t a�x the Pi to the 4CA, but just pre-vent it from flexing and touching any com-

ponents on it.

Fit in the cut wires into the Amplifier. For details check the illustration on the

next page.

STEP FOUR

17

Connect the power supply. Plug the power supply into a wall socket.

18

Make sure a red light turns on on the Raspberry Pi.

Unplug the power supply from the wall socket to further proceed with the

up-cycling.

19

Now prepare the SD card, by downloading its relevant software:

www.hifiberry.com/build/documentation/beocreate/beocreate-how-to-start/

Insert the SD card into the Raspberry Pi.

20

Place the electronics into the bottom of the speaker.

Screw on the back plate.

21

ENJOY

Your speaker is now physically upcycled.
